SHOCK ABSORBER.

Application filed. April 7, 1919. Serial No. 288,162.

Z '0 all whom it may concern Be it known that I, GEO-non F. VoIei-rT, a citizen. of the. United States, residing at San Francisco, in the county of San Francisco and State of California have invented a new and useful Improvement in Shock Absorbers. of which the following is a specification, the accompanying drawings forming a part thereof.

My invention relates to improvements in shock absorbers for road vehicles having transverse lea-f springs arranged to be inv the same vertical plane as the axles of the vehiclev An obj ect of my invention is to provide a yielding connection between the free ends of said leaf springs and. axles and wherebythe leaf springs may be assisted in cushioning the body of the vehicle against the unevenness of the roads over which it may travel.

Another object of the invention is to provide improvements over the invention disclosed in my United States Patent Number 1,267,609, granted May 28, 1918, and Number 1,294.3-53, granted February 11. 1919.

lVith the foregoing and other objects and purpose in view which will appear as the description proceeds. my invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention as herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings- Figure 1 is a view in elevation of a portion of the left-hand side of the front end of an automobile, showing the present invention applied thereto.

Figure 2 is a view in elevation of one of the levers forming a portion of the device.

Figure 3 is a view in elevation of a portiOn of the device detached from the rest of it.

Figure 4 is a sectional view on line (Ir- 0, Fig. 3. V

Figure 11 is aplan view of portions of the device. I

Figure 12 is aview on line f;, Fig. 11. Figure 13 is a view approximately in line ce, Fig. 1. I

Similar numerals of reference refer to similar parts throughout the several views. 1 designates the front axle of a vehicle, which is supported at one end by a wheel 2, and has rigidly secured to. its upper side a bracket 3. l

L is the vehicles front leaf spring which supports intermediate its ends a bed plate 5" and crank bearingfi. The leaf spring 4:. bed plate 5 and crank bearing 6 are rigidly clamped together by means of spring clips 7.

To facilitate in the description of the several elements and parts formingthe present invention, and in defining their position relatively to the vehicle,;the terms inner end or inner ends will designate the end or ends nearest the median center of the ve-.

hicle. and the terms outer end or outer ends will mean the end or ends farthest away from said center. s

8 designates a saddle plate having a substantially lower flat side seated upon the,

upper side of the bed plate 5 intermediate the outer end of the latter and the crank bearing 6, and is provided with a horizontally extending eye or opening, 9 rotatably supporting a pivot pin 10, and a vpair of downwardly struck lips 11 adapted to engage the sides of the bedplate 5 for limiting its transverse movements relatively to said bed plate The inner end of the saddle plate is intended to engage with the outer end of the crank bearing for preventing any inwardly movement of the former relatively to the latter.

12 designates a pair of laterally-spaced apart levers disposed one on each side of the leaf spring 1 and the upper end. of the bracket 3 and are provided with horizontal openings 13 (Figure 2) supporting the ends of a pivot pin 14 journaled in an opening 15 extending through the upper end of aid bracket 3; qpenings 16 of levers supthe ends oil a pivpt pin 1'? 5 openings 1.8 supporting a pin 18, and openings if) rigidly supporting a pin 20 adapted to hold the'leiiers intermediate their ends a definite distance apart.

To the outer ends of the pin 10 are secured the upper ends of a pair of oscillatory links 21 disposed one on each side of the bed plate 5 and leaf spring at and free to move relatively thereto. The lower ends of the links support the pin 18 the connection therewith being such that the links may rotate about the aris pin relatively to the levers l2,

22 represents a pair of oppositely arranged arc-shaped lips disposed one on each of the levers 12 (Figure 11) and said lips are provided with niarginal flanges said lips and flanges forin' a spring eat for the lower end of a spiralcompression spring 24. i

25 represents a spring hanger disposed between the levers 'la nterniediate their outer ends and said spring seat, and has a section provided with horizo tally extending opening 26 through which extends the pin 17, bywhich it pivotally supports the h g l Al pp l' s tion 9 1 extends above levers and has a faced portion 2? seated upon the upper end oi the compression spring 2i, and a lug; 28 projects centrallyfroni said faced portion and extends Tito opening or the upper end of the spring 2 land sec res said spring between han rs? at emp shri e e 29 is a eni attendee .h 'irwem ly through a section said hanger disposed below the levers 12 and supports the upper pin 30 of aspiring shackle 31, the lower pin 32 of the shackle supporting one end of the l a pr n Byreason of the pivoted connection of thehanger directly to the lever closely ad- .jacent was pivot point of the latter with the perch orbracket at which point the lever moves down slowly, the act on of the main spr ng, through the hanger, on the I auxiliary spring 2 3 is active p ro n pt,

ere ri siee t e as er-"r se ies qu c lv ic a tion he else t first ve ses s sreeie lr the outer end or" said hanger swings downwardly in a substantiz-ill axial direction to the auxiliary spring, as when the axis oi said spring is outwardly and upwardly in- .clined, whereby there little or no side thrust on said auxiliary spring, tending to dampen its action. The said hanger being pivoted to the same element on which the spring seat 22, 23 is formed tends to hold the outer end of said hanger in proper con1 pressing relation to said auxiliary spring.

1. In combination, a lever adapted at its outer end for pivotal support to a fixed bracket and adapted at its inner end to a movable support, and provided between its ends with a spring seat, a spring hanger adapted, between its ends, for connection to a main spring, and pivoted at its outer end to said lever between the pivotal end 0:? the lever and its spring seat, and provided in- Wardly beyond its pivot with a spring seat opposed to the spring seat; of said lever, and a" compression spring between said seats.

2. In combination, a lever adapted at its outer end for pivotal support to a iiJed bracket and adapted at its inner end to a rnovable support, and provided between its ends with a spring seat, a spring hanger adapted between its ends for connection to an end of a main spring, and pivoted at its outer end to said lever in *ardly beyond the pivotal end of the lever and provided in said lever inwardly beyond the pivotal end of the lever and provided inwardly beyond its pivot with an oblique inwardly and downwardly facing spring seat opposed to the spring seat of the lever, and an obliquely disposed coiled spring interposed between said seats.
